Abstract
This paper reports the results of a survey on estimated flood inundation depth at designated hospitals for infectious diseases in Japan based on open flood hazard maps. The results showed that inundation was expected at approximately a quarter of all target hospitals by floods of the designed level for river planning, while it was expected at about one-third of them by floods of the probable maximal level. Flood inundation deeper than 10 meters was expected at some hospitals, where self-protection measures such as evacuation to the upper stories or installation of the emergency power system to the upper level may no longer be effective. Close coordination with river authority, crisis management and public health authorities is therefore considered to be important for those hospitals to enlarge their capability of flood response.
